I have made A LOT of resin coasters through the years and this remains one of my all-time favorites!

There is a quick video tutorial at the end of this post, so you can see exactly how I did it!

• Resin
• When deciding on which resin to use for your coasters, you need to keep in mind whether you want it just for cold cups or for hot ones as well.
• If only for cold drinks, you can be flexible and use whatever brand you like:
  • Easy Cast
  • Art Resin
  • Clear Cast
• If you want it to work for both hot and cold drinks, you need to look for a heat-resistant resin, like these:
  • FX Poxy ~ According to the manufacturer, this one is heat resistant to 500° F.
  • Stone Coat

Liquid Rainbow Resin Coaster Directions

1.  Start with your coaster mold and take clear drinking straws and cut them to length. That way, they fit into the mold.

2. Pinch one end of the straw with pliers and take a lighter to melt the end together. Once it has melted, you should have a clean edge.

3. Mix water and food color. Then, drip the liquid into the straws. This is what will we will be putting in the resin coaster.

Do not fill them all the way because you want the water to have room to move around.

4. Take your lighter and seal the other edge.

5. Mix one ounce of resin and pour it into the silicone coaster mold and pop any bubbles with a lighter.

6. Place the filled straws into resin in the mold and let it cure for 12 hours.

*The reason you need to let the resin cure is if you were to add more resin before the first coat cured, the straws would likely float.

7. Mix more resin (1.5 – 2 ounces should do it) and pour it over the straws.

8. The straws should now be encapsulated in the resin. Use a lighter to pop the bubbles and then let it cure a minimum of 12 hours.

9. Once cured, pull it out of the mold!

HOW COOL IS THAT?!?!?!

Now, you have a resin coaster that has liquid flowing! You barely see the straws because they kind of blend in with the resin!

Finally, I want to make sure I give credit where credit is due! This video, by HelloMaphie, inspired this fun coaster!
